Description

  Embodiments described herein relate generally to a portable electronic device and a processing system for the portable electronic device.

  In general, an IC card used as a portable electronic device includes a card-like main body formed of plastic or the like and an IC module embedded in the main body. The IC module has an IC chip. The IC chip has a nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) or a flash ROM that can hold data even in the absence of a power source, and a CPU that executes various operations.

  The IC card is, for example, an IC card conforming to international standards ISO / IEC7816 and ISO / IEC14443. The IC card is excellent in portability and can perform communication with an external device and complicated calculation processing. Further, since it is difficult to forge, the IC card is assumed to store highly confidential information and be used for a security system, electronic commerce, and the like.

  In recent years, IC cards capable of transmitting and receiving data by non-contact communication have become popular. An IC card that performs non-contact communication as described above includes an IC chip and an antenna. An IC card operates by receiving a magnetic field generated from a reader / writer of an IC card processing apparatus that processes the IC card and causing an antenna in the card to generate electricity by electromagnetic induction. Further, when the IC card receives a command from the processing device by non-contact communication, the IC card executes an application according to the received command. Thereby, the IC card can realize various functions.

  The IC card processing device transmits an initial response request command by wireless communication at regular intervals. When receiving the initial response request command, the IC card generates a response to the initial response request command and transmits the generated response to the processing device. By receiving the response, the processing device can recognize that the IC card exists in the communicable range.

  The IC card holds an application field identifier (AFI). AFI is used by an IC card processing device to select an IC card according to the application field. For example, the processing device sets a value corresponding to the application field as AFI in the initial response request command. The IC card compares the AFI value set in the initial response request command with the AFI value held by itself, and sends a response to the processing device if they match. Thereby, the processing apparatus can process a desired IC card.

  However, when there are a plurality of IC cards having the same AFI in the communicable range of the processing device, the processing device may not be able to identify the IC card to be processed. For example, when an entry permit (visa) or the like is issued as an IC card, it is assumed that a plurality of IC cards having the same AFI are possessed by the user in a state where they overlap each other. In such a case, the processing apparatus has a problem that it is difficult to specify a desired IC card.

  Accordingly, it is an object of the present invention to provide a more convenient portable electronic device and a processing system for the portable electronic device.

  A portable electronic device according to an embodiment includes a receiving unit that receives an initial response request command transmitted from the external device, and a storage unit that stores in advance a plurality of applications each having an application field identifier and a different country code. Recognizing the application field identifier and country symbol from the received initial response request command, the recognized application field identifier and country symbol, and the application field identifier and country of each application stored in the storage unit A comparison unit for comparing symbols, and the application for which the comparison result of the comparison unit matches is generated to generate a response to the initial response request command, and the application for which the comparison result of the comparison unit does not match is executed If the comparison result of the command processing unit that does not match the comparison unit matches, the command processing The response generated and a transmitting unit that transmits to the external device by.

  Hereinafter, a portable electronic device, a processing device for a portable electronic device, and a processing system for a portable electronic device according to an embodiment will be described in detail with reference to the drawings.

  A portable electronic device (IC card) 20 and a processing device (terminal device) 10 for processing an IC card according to the present embodiment have a non-contact communication function defined by, for example, ISO / IEC14443. Thereby, the IC card 20 and the terminal device 10 can transmit and receive data to and from each other.

FIG. 1 shows a configuration example of an IC card processing system 1 according to an embodiment.
The IC card processing system 1 includes a terminal device 10 that processes the IC card 20 and an IC card 20. As described above, the terminal device 10 and the IC card 20 transmit and receive various data by non-contact communication.

  The terminal device 10 includes a CPU 11, a ROM 12, a RAM 13, a nonvolatile memory 14, a transmission / reception unit 15, a resonance unit 16, a logic unit 17, a host interface 18, and a power supply unit 19.

  The CPU 11 functions as a control unit that controls the entire terminal device 10. The CPU 11 performs various processes based on the control program and control data stored in the ROM 12 or the nonvolatile memory 14. For example, the CPU 11 transmits and receives commands and responses to and from the IC card 20 via the transmission / reception unit 15 and the resonance unit 16.

  The ROM 12 is a non-volatile memory that stores a control program and control data in advance. The RAM 13 is a volatile memory that functions as a working memory. The RAM 13 temporarily stores data being processed by the CPU 11. For example, the RAM 13 temporarily stores data to be transmitted / received to / from an external device via the transmission / reception unit 15 and the resonance unit 16. The RAM 13 temporarily stores a program executed by the CPU 11.

  The nonvolatile memory 14 includes, for example, EEPROM, FRAM (registered trademark), and the like. The nonvolatile memory 14 stores, for example, a control program, control data, an application, and data used for the application.

  The transmission / reception unit 15 and the resonance unit 16 are interface devices for communicating with the IC card 20.

  The transmission / reception unit 15 performs signal processing on data transmitted / received by the resonance unit 16. For example, the transmission / reception unit 15 performs encoding, decoding, modulation, and demodulation. The transmission / reception unit 15 supplies the encoded and modulated data to the resonance unit 16.

  The resonating unit 16 includes an antenna having a predetermined resonance frequency, for example. The resonance unit 16 generates a magnetic field according to data supplied from the transmission / reception unit 15. Thereby, the terminal device 10 can transmit data to the IC card 20 existing in the communicable range in a non-contact manner.

  The resonating unit 16 detects a magnetic field and generates data according to the detected magnetic field. Thereby, the resonance part 16 can receive data non-contactingly. The resonance unit 16 supplies the received data to the transmission / reception unit 15. The transmission / reception unit 15 demodulates and decodes the data received by the resonance unit 16. Thereby, the terminal device 10 can acquire the original data transmitted from the IC card 20.

  The upper interface 18 is an interface for communicating with the upper terminal. The host terminal includes, for example, an operation unit and a display unit. The operation unit includes an operation key, for example, and generates an operation signal based on an operation input by the operator. The display unit displays various information. The upper interface 18 receives data from the upper terminal and transmits it to the CPU 11. The upper interface 18 may be configured to transmit data acquired from the IC card 20 by the transmission / reception unit 15 and the resonance unit 16 to the upper terminal.

  The power supply unit 19 supplies power to each unit of the terminal device 10.

  The nonvolatile memory 14 includes a country symbol storage unit 14a that stores a country code (CC). The country symbol storage unit 14a stores, for example, a country symbol input from a host terminal via the host interface 18. Moreover, when the terminal device 10 has an operation unit that receives an operation input, the country symbol storage unit 14a may be configured to store a country symbol corresponding to an operation input to the operation unit. Further, the ROM 12 may include a country symbol storage unit 14a. The country symbol will be described later.

FIG. 2 shows a configuration example of the IC card 20 according to one embodiment.
As shown in FIG. 2, the IC card 20 includes, for example, a rectangular main body 21 and an IC module 22 built in the main body 21. The IC module 22 includes an IC chip 23 and a resonance unit (antenna) 24. The IC chip 23 and the resonance unit 24 are formed in the IC module 22 in a state where they are connected to each other.

  The main body 21 is not limited to a rectangular shape, and may have any shape as long as the IC module 22 in which at least the resonating portion 24 is disposed can be installed.

  The IC chip 23 includes a CPU 25, a ROM 26, a RAM 27, a nonvolatile memory 28, a transmission / reception unit 29, a power supply unit 31, a logic unit 32, and the like. The CPU 25, the ROM 26, the RAM 27, the nonvolatile memory 28, the transmission / reception unit 29, the power supply unit 31, and the logic unit 32 are connected to each other via a bus.

  The resonance unit 24 is an interface for communicating with the resonance unit 16 of the terminal device (external device) 10. The resonating unit 24 includes, for example, an antenna formed of a metal wire disposed in a predetermined shape in the IC module 22.

  The IC card 20 generates a magnetic field by an antenna according to data transmitted to the terminal device 10. Thereby, the IC card 20 can transmit data to the terminal device 10. Further, the IC card 20 recognizes data transmitted from the terminal device 10 based on an induced current generated in the antenna by electromagnetic induction.

  The CPU 25 functions as a control unit that controls the entire IC card 20. The CPU 25 performs various processes based on the control program and control data stored in the ROM 26 or the nonvolatile memory 28. For example, various processes are performed in accordance with commands received from the terminal device 10 and data such as responses as processing results is generated.

  The ROM 26 is a non-volatile memory that stores a control program and control data in advance. The ROM 26 is incorporated in the IC card 20 in a state where a control program, control data, and the like are stored at the manufacturing stage. That is, the control program and control data stored in the ROM 26 are incorporated in advance according to the specifications of the IC card 20.

  The RAM 27 is a volatile memory that functions as a working memory. The RAM 27 temporarily stores data being processed by the CPU 25. For example, the RAM 27 temporarily stores data received from the terminal device 10 via the resonance unit 24. The RAM 27 temporarily stores data to be transmitted to the terminal device 10 via the resonance unit 24. Furthermore, the RAM 27 temporarily stores a program executed by the CPU 25.

  The non-volatile memory 28 includes a non-volatile memory capable of writing and rewriting data, such as an EEPROM or a flash ROM. The nonvolatile memory 28 stores a control program and various data according to the usage application of the IC card 20.

  For example, in the nonvolatile memory 28, a program file and a data file are created. A control program and various data are written in each created file. The CPU 25 can implement various processes by executing programs stored in the nonvolatile memory 28 or the ROM 26.

  The transmission / reception unit 29 performs signal processing such as encoding and load modulation on the data transmitted to the terminal device 10. For example, the transmission / reception unit 29 modulates (amplifies) data to be transmitted to the terminal device 10. The transmission / reception unit 29 transmits the data subjected to signal processing to the resonance unit 24.

  The transmission / reception unit 29 demodulates and decodes the signal received by the resonance unit 24. For example, the transmission / reception unit 29 analyzes a signal received by the resonance unit 24. As a result, the transmission / reception unit 29 acquires binary logical data. The transmission / reception unit 29 transmits the analyzed data to the CPU 25 via the bus.

  The power supply unit 31 generates power based on radio waves (for example, carrier waves) received by the resonance unit 24. Furthermore, the power supply unit 31 generates an operation clock. The power supply unit 31 supplies the generated power and operation clock to each unit of the IC card 20. Each unit of the IC card 20 becomes operable when supplied with power.

  The logic unit 32 is an arithmetic unit that performs arithmetic processing by hardware. For example, the logic unit 32 performs processing such as encryption, decryption, and random number generation based on a command from the terminal device 10. For example, when receiving a mutual authentication command from the terminal device 10, the logic unit 32 generates a random number and transmits the generated random number to the CPU 25.

  In addition, the nonvolatile memory 28 includes a country symbol storage unit 28a that stores a country symbol. The country symbol storage unit 28a stores, for example, a country symbol that is input from the outside when the file of the IC card 20 is created. Further, the ROM 26 may include a country symbol storage unit 28a. In this case, the ROM 26 is incorporated in the IC chip 23 in a state where the country code is stored. When the nonvolatile memory 28 stores a plurality of applications, the country symbol storage unit 28a may be configured to store a country symbol for each application. The country symbol will be described later.

  The IC card processing device transmits an initial response request command by wireless communication at regular intervals. When receiving the initial response request command, the IC card generates a response to the initial response request command and transmits the generated response to the processing device. By receiving the response, the processing device can recognize that the IC card exists in the communicable range.

  The IC card holds an application field identifier (AFI). AFI is used by an IC card processing device to select an IC card according to the application field. For example, the processing device sets a value corresponding to the application field as AFI in the initial response request command. The IC card compares the AFI value set in the initial response request command with the AFI value held by itself, and sends a response to the processing device if they match. Thereby, the processing apparatus can process a desired IC card.

  The terminal device 10 illustrated in FIG. 1 transmits an initial response request command by wireless communication at regular intervals by the resonance unit 16. Thereby, the terminal device 10 recognizes the IC card 20 existing within the communicable range and performs settings related to communication. The terminal device 10 adds an application field identifier (AFI) and a country symbol (CC) to the initial response request command.

FIG. 3 shows an example of an application field identifier according to an embodiment.
The AFI is an identifier used by the terminal device 10 to specify an application field. AFI is a value expressed by, for example, 8 bits (1 byte). The terminal device 10 stores in advance the AFI value corresponding to the field in which the terminal device 10 is used, for example, by the ROM 12 or the nonvolatile memory 14. The terminal device 10 sets the AFI value stored in the initial response request command.

  Further, the IC card 20 stores in advance, for example, the ROM 26 or the nonvolatile memory 28 according to the field in which the IC card 20 is used. When the IC card 20 receives the initial response request command, the IC card 20 compares the AFI value of the initial response request command with the AFI value stored in the IC card 20, and performs a subsequent process if they match. That is, the IC card 20 ends the process when the AFI value of the initial response request command does not match the AFI value stored in itself. Thereby, the terminal device 10 can narrow down the IC cards 20 corresponding to the terminal device 10.

  As illustrated in FIG. 3, for example, when the terminal device 10 is used in the transport field (Transport), the terminal device 10 stores “10” or “1Y” as the AFI. The terminal device 10 sets a value of “10” or “1Y” as the AFI in the initial response request command, and transmits the initial response request command. When receiving the initial response request command, the IC card 20 checks whether the AFI value stored in itself is “10” or “1Y”. When the value of the AFI stored in the IC card 20 is “10” or “1Y”, the IC card 20 performs subsequent processing.

  Further, for example, when the terminal device 10 is used in the financial field (Financial), the terminal device 10 stores “20” or “2Y” as the AFI. The terminal apparatus 10 sets a value of “20” or “2Y” as the AFI in the initial response request command, and transmits the initial response request command. When receiving the initial response request command, the IC card 20 checks whether the AFI value stored in itself is “20” or “2Y”. When the value of the AFI stored in the IC card 20 is “20” or “2Y”, the IC card 20 performs subsequent processing.

FIG. 4 shows an example of a country symbol (CC) according to an embodiment.
CC is an identifier indicating a country name (including a region name). CC is a value expressed in 16 bits (2 bytes), for example, as defined in ISO / IEC3166-1. The IC card processing system 1 associates CC values with country names in advance, and sets a country symbol table as shown in FIG. Thereby, a country name can be specified from the value of CC.

  The terminal device 10 stores the CC value in advance in the country symbol storage unit 14a based on the country symbol table, for example. For example, the terminal device 10 stores in advance a CC value corresponding to the country in which the terminal device 10 is operated. The terminal device 10 sets the CC value stored in the initial response request command.

  Further, the IC card 20 stores the CC value in advance in the country symbol storage unit 28a based on the country symbol table. When the IC card 20 receives the initial response request command, the IC card 20 compares the CC value of the initial response request command with the CC value stored in the country symbol storage unit 28a. Do. That is, the IC card 20 ends the process when the CC value of the initial response request command does not match the CC value stored in the country symbol storage unit 28a. Thereby, the terminal device 10 can further narrow down the IC cards 20 corresponding to the terminal device 10.

  As illustrated in FIG. 4, for example, when the terminal device 10 is used in the United States (United States), the terminal device 10 stores “840” as the value of CC. The terminal device 10 sets “840” as the CC value in the initial response request command, and transmits the initial response request command. When receiving the initial response request command, the IC card 20 checks whether the CC value stored in the IC card 20 is “840”. When the CC value stored in the IC card 20 is “840”, the IC card 20 performs subsequent processing.

  For example, when the terminal device 10 is used in Iceland, the terminal device 10 stores “352” as the value of CC. The terminal device 10 sets “352” as the CC value in the initial response request command, and transmits the initial response request command. When receiving the initial response request command, the IC card 20 checks whether the CC value stored in the IC card 20 is “352”. When the CC value stored in the IC card 20 is “352”, the IC card 20 performs subsequent processing.

FIG. 5 shows an example of an initial response request command transmitted by the terminal device 10.
As shown in FIG. 5, the initial response request command has “APf”, “AFI”, “CC”, “PARAM”, and “CRC_B”.

  APf is a parameter used in the initial response request command. APf is, for example, 1-byte data.

  As described above, the AFI is an identifier used by the terminal device 10 to identify the application field. AFI is a value expressed by, for example, 8 bits (1 byte). That is, the terminal device 10 sets the AFI value in the 9th to 16th bits from the beginning of the initial response request command.

  As described above, CC is an identifier indicating a country name (including a region name). CC is a value expressed by 16 bits (2 bytes), for example. That is, the terminal device 10 sets the CC value at 17 bits to 32 bits from the beginning of the initial response request command.

  PARAM is a parameter of attribute information. PARAM is, for example, 8-bit (1 byte) data. PARAM indicates the type of command and the number of slots used in anti-collision such as a slot marker method or a time slot method.

  CRC_B is a cyclic redundancy check code. CRC_B is a value expressed by 16 bits (2 bytes), for example. CRC_B is a value calculated from data bits in a frame having a command including CRC_B as a character. The IC card 20 determines whether or not the received command is normally transmitted using the CRC_B of the received command.

FIG. 6 shows an example of the operation of the IC card 20 according to one embodiment.
First, the terminal device 10 repeatedly transmits an initial response request command to the communicable range by the resonance unit 16 in order to detect the IC card 20.

  When the IC card 20 enters the communicable range of the resonance unit 16 of the terminal device 10, the IC card 20 is activated and enters an idle state (step S11). Further, the IC card 20 receives the initial response request command (step S12).

  The CPU 25 of the IC card 20 analyzes the received initial response request command. As a result, the CPU 25 recognizes the values of the initial response request commands “APf”, “AFI”, “CC”, “PARAM”, and “CRC_B”.

  The CPU 25 determines whether or not the recognized AFI value of the initial response request command matches the AFI value stored in the ROM 26 or the nonvolatile memory 28 of the IC card 20 (step S13).

  If the recognized AFI value does not match the AFI value stored in the IC card 20, the CPU 25 proceeds to step S12 and waits for reception of an initial response request command. Thereby, the IC card 20 that does not correspond to the application field specified by the terminal device 10 is excluded from the processing target.

  When the recognized AFI value matches the AFI value stored in the IC card 20, the CPU 25 determines the CC value of the recognized initial response request command and the CC stored in the country symbol storage unit 28a. It is determined whether or not the values match (step S14).

  If the recognized CC value does not match the CC value stored in the IC card 20, the CPU 25 proceeds to step S12 and waits for reception of an initial response request command. Thereby, the IC card 20 that does not correspond to the country symbol specified by the terminal device 10 is excluded from the processing target.

  When the recognized CC value matches the CC value stored in the IC card 20, the CPU 25 generates a response to the initial response request command and transmits it to the terminal device 10 (step S15). Thereafter, the IC card 20 and the terminal device 10 perform normal processing (step S16). That is, the IC card 20 and the terminal device 10 perform anti-collision processing, mutual authentication processing, normal command processing, and the like by transmitting and receiving commands and responses to each other.

  The IC card processing system 1 according to the above-described embodiment includes the terminal device including the country symbol storage unit 14a and the IC card 20 including the country symbol storage unit 28a. The terminal device 10 sets the country symbol (CC) stored in the country symbol storage unit 14a to the initial response request command and transmits it. The IC card 20 compares the CC value set in the initial response request command with the country code stored in the country code storage unit 28a. The IC card 20 transmits a response to the terminal device 10 when the comparison results match.

  Thereby, the IC card 20 that does not correspond to the CC specified by the terminal device 10 is excluded from the processing target. For this reason, even if there are a plurality of IC cards 20 used in a specific application field in the communicable range of the resonance unit 16 of the terminal device 10, the terminal device 10 must specify a desired IC card. Can do. As a result, collision and the like can be suppressed, and a more convenient portable electronic device, a processing device for the portable electronic device, and a processing system for the portable electronic device can be provided.

  In the above embodiment, CC is a value expressed by 16 bits (2 bytes), but is not limited to this configuration. The amount of CC data is appropriately set according to the number of country names to be identified. For example, if CC is 8 bits (1 byte), 256 values can be expressed. For this reason, when it categorizes only by country name, CC may be 1-byte data. In addition, when it is classified by Europe, North America, South America, Asia, Africa, etc., it can be expressed in about 4 bits.

  Furthermore, by making CC larger than 2 bytes, it is possible to classify even a small region in the country. In this case, for example, the terminal device 10 can identify a traffic IC card used in the Kansai region of Japan and a traffic IC card used in the Kanto region of Japan. As a result, the chance of collision can be further reduced.

  It should be noted that the functions described in the above embodiments are not limited to being configured using hardware, but can be realized by causing a computer to read a program describing each function using software. Each function may be configured by appropriately selecting either software or hardware.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
